Download file to see previous pages Concrete pavements are durable surfaces that are laid down on roads and walkways primarily to sustain vehicular or foot traffic. Throughout the history, Concrete has always been as one of the most durable, cheap and reliable materials for conventional pavements found in the highways, streets, airports as well as residential and business parking areas. This is particularly attributed to the various properties of Concrete such as workability, strength and durability. For example, apart from offering the best riding surface, concrete is also widely believed to be economical, durable and sustainable solution for most surfaces (Shackel, 2008)
Generally, there are currently two main methods of making concrete pavements namely the slip form and the fixed form paving. In the slipform paving method, machine usually rides on the treads over a particular area to be paved before fresh concrete is deposited on the paved surface. Next, a paving machine is then used to spread, screed and consolidate the concrete into a continuous operation. On the other hand, fixed-form paving involves setting and aligning stationary metal forms on solid foundation and then rigidly staking them.
Concrete is then spread using a mechanical spreader before it is consolidated, finished and cured. After putting the finish to the concrete pavements, joints are should be created in order to help control cracking as well as to provide a system of relief for the potential concrete expansion due to moisture or temperature changes. In most cases, joints are usually created by sawing. Lastly, the surface is then textured before the concrete is completely dry in order to provide some form of skid resistance.
Thickness of concrete pavements should be designed such that the stress and strains developed is less than allow able measurements gotten from prior performance information. The design of the pavement must keep moisture out of the sub base, capping, and subgrade ...Download file to see next pagesRead More

Concrete Constituent and Mix Design

...? Concrete Constituent and Mix Design Q Concrete is basically made up from cement, aggregate and water. Aggregate occupy about 65 – 80% of the total concrete volume. Hence, its role/function and properties influence the overall performance of concrete. a) Describe briefly the three different types of aggregate. Heavy weight aggregate Normal weight aggregate Light weight aggregate Answer To Q-1 Heavy Weight Aggregates Heavyweight aggregates are used to make heavyweight concretes, with unit weights ranging from about 2900 to 6000 kg/m3. Such concretes are used primarily for radiation shielding, but they are sometimes used...

The effectiveness of dowel bars in concrete pavements

...from the theory behind these bars to how they ought to their proper placement in the joints. Stresses in Concrete Pavement A concrete pavement is generally referred to as a rigid pavement. It is multilayered with layers being placed on top of each. The strength of the layers decreases downwards. Figure 1 (Pavement Analysis and Design n.d) The major factors that subject concrete pavements to stresses are “the action of traffic wheel loads, the expansion and contraction of the concrete due to temperature changes, yielding of the subbase or subgrade...

Design and construction of a prestressed concrete tank

...?Design and construction of a prestressed concrete tank Introduction Prestressed concrete tank did not come out as an acknowledged building material up to a half-century later despite it being patented by an engineer of San Francisco in 1886. The scarcity of steel in Europe subsequent to World War II together with technological improvements in high-strength steel and concrete made prestressed concrete tank a building material of choice throughout European post-war reconstruction. The first prestressed concrete structure of North America, Walnut Lane Memorial Bridge located in Philadelphia, Pennsylvania, nonetheless, was not completed...

Pumping Concrete

...resolved by reducing the air in the mix design. [3] Plasticizers Superplasticizers or High Range Water Reducers are plant added water-reducing admixtures which produces a high slump, flowing concrete. They are ideal and usually necessary for pumping concrete, producing high strength concrete, and enabling concrete to flow around tightly matted rebar. [6] Conclusion Concrete has been used since times immemorial and its importance can be judged by the fact that it is still being used today as a primary agent in constructing buildings and structures. But as time is passing by, newer technology is shaping new paths for us to follow....

Design Analysis

...Design Analysis: Apple Logo Introduction We are often come across with thousands of designs and visuals in our daily life. We come across with many advertisements and visuals designed by different creative artists or designers while we reading news papers or magazines, viewing the televisions programs and surfing the internet. In fact most of the organizations and business groups have their own corporate logos in order to segregate them in the market. Consumers are well aware of the corporate logos and they make their purchases based on the brand names. Logos have a definite role in building the brand. This paper briefly analyses Apple company logo and...

Materials: Concrete Durability Design

...MATERIALS: CONCRETE DURABILITY DESIGN In a discussion of the suitability of all of the available materials for use in the concrete the following is involved. The water is more suitable as it meets the specifications of ASTM C94. The requirements cover for concrete that is already mixed produced and dispatched to a buyer in newly mixed and unhardened form as specified. The concrete quality requirement according to ASTM C94 specification is either specified according to purchase or as specified (Lamond 2006). In cases where purchaser’s requirements differ, the specification of buyer shall rule. In case of selected applicable materials’ absence, the...

Analysis and design of concrete pavements

...Analysis and Design of Concrete Pavements Full (s) ENS4321 07 May Concrete is increasingly becoming one of the most widely used paving material for airports, highways, residential streets as well as business parking lots in Australia. This is particularly attributed to the numerous potential benefits of using concrete as a paving material some of which include its durability and less maintenance requirement, workability, strength, cost effectiveness and durability. Modern Australian and International designs for concrete pavements are largely based on a number of factors including the...

...Case Study: Concrete Introduction The urge of humankind to find a strong shelter that can save people from natural disasters like storms and snow or rain, has made concrete attractive for many generations until now. The development of blended mixture for use in buildings dates back to almost 3000 years. Egyptians used this technology, which is evident from the construction of pyramids by them, many years back. Syrians used concrete even before Egyptians did. However, the Roman Empire refined the use of concrete mixture, which involved blending process somewhat similar to the present technique. Concrete remains the most essential part of our daily...

Concrete is a very common construction material. In Concrete Design, you learn the positives and negatives using concrete during construction

... easier to retrofit the conceptualization, planning and design stage of the structures have to be clearly well thought out. This means the developers and the architects have to consider both the short and long-term uses of the structures. In addition, alternatives can be found in parts of structures that do not require concrete. For example, columns, pillars, beams require the use of concrete, on the other hand, wood or steel can be used for partitioning and floors. References Flint, A. (2014, November 18).
